The present invention relates to furnace attachments for supplying liquid, such as water to the fuel during the process of burning for enhancing the combustion thereof.

It is a known fact that fuel when dry burns quickly, and therefore a further object of the present invention is the provision of an attachment to be used in furnaces whereby water may be supplied and caused to drip '10 in small quantities'upon the burning fuel to retard the fast combustion thereof.

Another object of the present inventionis v the provision of an attachment of the charf acter indicated for supplying water to the burning fuel, which in addition to'retarding the fast combustion of the fuel would act upon theemitting smoke and soot for moistening the same and consequently for preventing its escape before the same is com- 7 pletely consumed.

With the above general objects in view and others that will appear as the invention is better understood, the same consists in the novel construction, combination and arrange- :2 ment of parts hereinafter more fully de- Fig. 3 is a top plan view of a modified form of the device. I

Referring in detail to the present drawing there is shown a furnace 10 having grate 11 upon which fuel 12 is intended to burn. Said furnace is further provided with a smoke pipe 13. I

My invention best illustrated on Fig. 2 includes four pipes 14 arranged crosswise and connected at their inner ends by cross union 15. Each of said pipes 14 at its outer ends I pipe into union 15. and from there the water is upper portions. are provided with a series of minute apertures or openings 22 through which water is adapted topass and upwardly spray and, thereupon drop to the burning upon the emitting. smoke and unconsumed as to'j prevent their ready'gescape through carries T-pipe union 16 to which apair of smoke pipe 13 and consequently to facilitate inwardly curving pipes 17 are attached. Each correspondingpair of said pipes 17 present an appearanceof a horse-shoe. The ends of said pipes 17 are provided with caps 18. 7

An -L-shaped pipe, including a'hori'zontal portion 19 and a short vertical leg'portio'n 20, is attached by one of its ends to cross union '15. At the latters upright end integrally formed and upwardly extendingis projection 21. The other end of said L-shapedpipe passes throughthe wall of the furnace and is connected to a water supplying source such as city pipes. v s i 1 Water is supplied through said L-"shaped 5 distributed among pipes 14 and from there the same is passed through the several curving pipes 17. Said pipes 14 and 17 at their fuel'12. a p

. The amount of water passing throughJpipes 14 and 17 or its degree of pressureor the degree of its spraying may 'be'regulated by a pressure controlling device such as a valve which may be positioned upon the horizontal portion 19 of the L-shaped pipe andoutwardly of thefurnace 10. A

i The modifiedform-of the inventiomillustratd on Fig. 3, includes a spirally arranged pipe 23, provided upon its upper portion with a number of openings 22 The outer end of said pipe 23 carries cap 18' To the inner 5 end of said pipe 23 an L-shaped pipe such as 1920, may be aflixed for supplying water to said pipe 23. I 7 r i From the'hereinabove description it will be seencthat waterpassing through openings '22, or 22' and dripping upon fuel 12 willretard the combustion whenv thefuelzis-dry,

and which would otherwise bequickly consumediand at the same time' said water acts particles of the fuel, which would otherwise escape with lthesmoke, for moistening the' same; and thus for increasing their weightso ment facilitatesthe uniform'distribution of the pp Water thmv-gllnu ztheteen e V andthroughout the surface of the burning i fuel.
